Randy Sarafan has helped the human race hit a new ‘all-time low’ on the evolutionary scale. He has modified his office chair with technology that will detect when he emmits a gasous cloud from his anus and it ranks it on methane density. It then transmits this information through his Twitter account to all his followers (which stand at 200 sick folks right now).
The setup is surprisingly simple and there is even an online guide so you can create your own. It involves, a natural gas sensor does the sniffing; an Arduino does the thinking; an XBee wireless module does the communicating; Twitter does the sharing. It’s a feat, to be sure.
